I have a a first model .22 tip-up single shot target.
SN 22367.
I have tried a few different types of ammo, and most bullets shot from it seem to tumble and keyhole.....while a very few make the anticipated .22-sized round hole in a paper target.
As such, it seems the barrel (which has very pitted rifling) is shot out.
Does anyone reline these barrels.....ideally with the later Olympic rifling that requires a firm thumb to seat the round fully?
Any hints, ideas, or leads appreciated.
Thanks in advance.
